WINDOW-BURGLAR-PROOFING DEVICE.

70 @ZZ tu/ioni, it may concern.'

le it known that I, OSnonNn H. Sinin Pano, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in lVindow-Burglar-Proofing Devices, of which. the following is a specification.

My invention relates to an improvement in the class of devices used for obstructing the upper and lower sashes of windows, when partly opened for ventilation, against being farther opened sutliciently to permit entry through the opening into the inclosure to be protected.

A deviee of the kind referred to, and upon which, particularly, it is my ohject to iinprove with a view to increasing its safety` resembles a hinge having two pintle-connected leaves. One leaf is adapted lo be fastened to the inner face of a side rail of the upper sash, and the other leaf folds against it when it is desired to leave the sashes free to be opened. rlhe device is thus fastened at a sufficiently low point on the upper sash, so that when the free leaf is turned to extend at an angle to the fastened leaf to project into the path of the up per rail of the lower sash, it will act as a stop against raising the latter and lowering the upper sash farther than is required for ventilation, but not far enough for the entry of a burglar through either opening. The device is further provided with latching-means for locking the swinging leaf in its stopping position. This device does not afford an adequate degree of safety, how ever, because it is a comparatively easy Inatter to reach it from the outside, either through the openings afforded by the partially-opened sashes, or through an opening cut in the window-glass, to unlock the latch, when the stop-leaf may be readily turned aside to permit farther opening of the window.

My improvement is designed to overcome this objection and increase the safety function of the device.

In the accompanying drawing, Figure 1 is a broken perspective View showing my im proved device in its operative position; Fig. 2 is an inner face View of the device, showing the hingedeaves spread apart to their fullest extent; Fig. 3 is a similar view of the same showing the swinging hinge-leaf extending at right-angles to the xed leaf, and

Specification of Letters Patent.

Application filed July 21, 1913.

Fig. 4lis an enlarged broken section on line l, Fig. 2.

A hinge of suitable size, comprises two leaves, (l and 7, one of which is shown to be providinl with holes, through which to screw or nail it to a side-rail of an upper windowsash 8, as represented in F ig. l. The other, swinging, leaf may be imperforate, except for a single hole, in which works a removable stop, shown in its preferred form of a set-screw t); this being the gist of my improvement. On the inner face of the swinging leaf is fastened a wire spring .l0 having a flattened. or knife-edge section ll, and projecting beyond the outer edge of the leaf to alford a handle 1Q. The spring extends above the set-screw. close to the face of the leaf, so that when the screw is adjusted the `flat springssection ll engages its thread close to the leaf-surface and locks the setscrew against longitudinal movement.

With the device secured in place on the upper window-sash. and the set-screw re moved, the swinging leaf may be -folded against the fastened leaf to present no obstruction to raising the lower sash or lowering` the upper one to the full or to any desired extent. To set the device for performing its lnirglar-proof function. the set-screw is inserted into the hole provided for it in the swinging leaf. The inner end of the set-screw then will abut. in any attempt to fold the leaf 7 against' the adjacent face of the fastened leaf, and prevent removal of the swinging leaf out of the path of the lower sash, and the outer end of the setscrew prevents turning the swinging leaf outwardly to take it out of that path, since that end will strike the inner side of the window-frame in any attempt to do so, thereby insuring the projection of the swinging leaf, as a stop, over the path of the upper rail of the lower sash, to prevent raising it unduly high and lowering the upper sash to an undue extent. In adjusting the setscrew into its operative position, the spring l0 is held raised to separate it from the threads, and when the stop is properly adjusted the spring is released to engage a thread and lock the stop; and the latter may be readily withdrawn, at the inner side of thel window, to render the device inoperative for its purpose, upon straining the spring out of Contact with the threads and holding it there pending the withdrawal.

The spring lock for the stop 9 is an adjunct in enhancing security of the device against tampering, because a burglar working from the outside through the partiallyopened window, or througha hole made for the purpose in the window-pane, can not well use more than one hand. VVithhis'oiie hand he might, in the absence of the springloclr, succeed in withdrawing the set-screw, though the attempt would be attended with great difficulty in manipulatingv it, at its head, in the narrow space between the swinging leaf and the adjacent face of the window-frame. However, with the spring in operation he could not, with' one hand, hold its out of engagement with the stopthreads and at lthe saine time manipulate the stop to remove it; so that the attempt :I would be wholly frustrated.

YVhatI claim as vnew and desire to secure byLetters Patent is` 1..A` device of the character described, comprising a hinge having a leaf adapted tobe fastened toran upper window-sash, and

the' other, swinging, leaf to be folded, will, against the fastened leaf or projected at an angle thereto into the pathV of the lower sash, and a stop projecting transversely' through the swinging leaf, for the purpose` set forth.

2. A device of the character described, comprising a hinge having a leaf adapted to be fastened to an upper window-sash, and

I another, swinging, leaf to be folded, at will,

against the fastened leaf or projected at an angle thereto int-o the path of they lower sash, and a removable stop passing transverselyrthrough the swinging leaf and projecting at opposite sides thereof,for the purpose set forth. j

3. Afdevice of the character described, comprising a hinge havingV a leaf adapted to be fastened to an upper window-sash, and another, swinging, leaf to be folded, at will,

against the fastened leaf or projected at an angle'thereto int-o lthe vpath of the loweiq sash, and a set-screw working through the swinging leaf, forftlie purpose set forth.

t. A device of the character described,
